As a guy new to hockey, I figured I'd share my experience since this seemed like the appropriate thread. I started out skating about 6 weeks ago on a new pair of CCM U+07's. These were initially sharpened with a 10' radius, 1/2" hollow (I hope I have these details right...still learning the lingo). Since then I've been going to the rink about twice a week and making some good progress. However, I always felt like the skates had too much bite for me. So yesterday I tried out the 90/75 cut at East West Hockey (across the street here in San Jose from the Sharks Ice Center). My only input to the guy doing the work was that I wanted something with a bit less bite, thus his recommendation to go with the 90/75. Once finished I went across the street and hit the rink. There was an immediate difference in my ability to stop. This had been a weakness of mine in the past; I used to feel like I was almost fighting with the skate to make it slide across the top of the ice when trying to stop. By the end of the session my confidence had grown tremendously. As I get better I may move to trying the 100/50 profile, but for now I'm enjoying the gains in my abilities just based on a different edge profile. Had I not been able to do some research on this message board I probably never would have tried this out. Thanks!
